Luminosity functions of nearby young open clusters

Nearby open clusters play a benchmark role in the observations related to the fundamental astrophysical processes, such as formation and evolution of stars and their planets. We used Gaia DR3 catalogue to place stars in the position-velocity space and re-evaluated memberships of young (<1Gyr) open clusters in the vicinity of the Sun (<500 pc). We re-examined their relative ages revealed from their colour-magnitude diagrams and rotation periods from the TESS data. This enables us to study the evolution of the luminosity function over time and speculate about the gradual evaporation and dispersal of their members into the Galactic disk.
With the goal to make these results widely available to the professional and amateur communities, we are building a website with our catalogues of cluster members linked to Aladin and CDS virtual observatory tools. An interactive plots of our members offer an opportunity for users to create their personalised 3D plots and colour-colour diagrams.
